IfcReinforcementDefinitionProperties defines the cross section properties of reinforcement included in reinforced concrete building elements. The property set definition may be used both in conjunction with insitu and precast structures.
This subtype of IfcPropertySetDefinition is used to define the reinforcement properties in early design stages, such as in requirement definition or scheme design. In later design stages explicit instances of subtypes of IfcReinforcingElement are used. The intended usage may be indicated using the DefinitionType attribute value as a designator: recommended values are 'Reinforcement area requirement' or 'Reinforcement configuration requirement'. Other values may be used according to local standards.
Only one property set definition of this kind is used for each concrete building element in each intended usage indicated by the DefinitionType attribute value. This set then defines a list of cross section properties in a discrete number of longitudinal sections as instances of IfcSectionReinforcementProperties (one for each structural reinforcement bar role), which in turn have a section cross section property defined as a profile and a number of reinforcement properties, one for each steel grade / bar type.
Assignment of a globally unique identifier within the entire software world.
Assignment of the information about the current ownership of that object, including owning actor, application, local identification and information captured about the recent changes of the object,
Optional name for use by the participating software systems or users. For some subtypes of IfcRoot the insertion of the Name attribute may be required. This would be enforced by a where rule.
Optional description, provided for exchanging informative comments.
|HasContext||SET [0:1] OF IfcRelDeclares FOR RelatedDefinitions|
|HasAssociations||SET [0:?] OF IfcRelAssociates FOR RelatedObjects||
Reference to the relationship IfcRelAssociates and thus to those externally defined concepts, like classifications, documents, or library information, which are associated to the property definition.
|DefinesType||SET [0:?] OF IfcTypeObject FOR HasPropertySets||
The type object to which the property set is assigned. The property set acts as a shared property set to all occurrences of the type object.
|IsDefinedBy||SET [0:?] OF IfcRelDefinesByTemplate FOR RelatedPropertySets||
Relation to the property set template, via the objectified relationship IfcRelDefinesByTemplate, that, if given, provides the definition template for the property set or quantity set and its properties.
|DefinesOccurrence||SET [0:?] OF IfcRelDefinesByProperties FOR RelatingPropertyDefinition||
Reference to the relation to one or many object occurrences that are characterized by the property set definition. A single property set can be assigned to multiple object occurrences using the objectified relationship IfcRefDefinesByProperties.

Descriptive type name applied to reinforcement definition properties.
|6||ReinforcementSectionDefinitions||LIST [1:?] OF IfcSectionReinforcementProperties||
The list of section reinforcement properties attached to the reinforcement definition properties.
Ownership, history, and merge state is captured using IfcOwnerHistory.
IfcRoot assigns the globally unique ID. In addition it may provide for a name and a description about the concept.
